It is the operating system that powers many of the company's mobile devices, including the iPhone; the term also included the versions running on iPads until iPadOS was introduced in 2019, as well as on the iPod Touch devices, which were discontinued in mid-2022. After Android, it is the world's second-most widely installed mobile operating system. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts are open source under the Apple Public Source License and other licenses.
